In the game's opening cutscene, Navi the fairy is seen soaring through Kokiri Forest until she arrives to her destination - Link's house. She was ordered by the Great Deku Tree to bring Link to him, though before doing so Link was required to come in possession of a sword and a shield, both of which can be found in the village. Once the summoned subject arrives, the Great Deku Tree explains how he was cursed by the villain Ganondorf.
Link tries to his heart's content to save the tree by entering inside of him and dispatching the source of the curse bestowed upon him - Gohma, though the tree was inevitably going to perish because of it, and thus did so before telling Link his journey in which he would have to partake in order to save the world. His parting words were to tell Link to head straight to Hyrule Castle, and before dying gives him a spiritual stone - one of three.
After traveling through Hyrule Field and subsequently entering Hyrule Castle Town, he heads towards the castle and passes by the guards. Upon entering the castle, he meets Princess Zelda, who, like Link, is nothing but a child.
She tells Link of her foretelling dream of an evil man upon a black clad horse - the one who cursed the Great Deku Tree to his death, and tells Link of the impending doom upon their land that she witnessed in her dream. She trusts that none will believe her, and requests that Link does and find the remaining two stones that are in the possession of the Gorons and the Zora.
